I just want to add this to the first two posts above.
The bitcoin transaction is irreversible yeah I agree if the transaction is already confirmed but if not yet confirm you can able to reverse the transaction by making a double-spend transaction. So that the first transaction that you send to scammer address you can rebuild the transaction and send it back to your own address but this time make sure to increase the transaction fee so that the new transaction will be confirmed and the old transaction will be rejected.

This only works if the transaction is RBF enabled and if the transaction still unconfirmed due to a low fee.

So this is the error "Error: Cannot load wallet(1): UnicodeDecodeError('UTF-8', )" that you get when trying to import the old 2010 wallet to Electrum 4.1.2?

I hope that the file is not corrupted and next time before you do anything about your backup wallet make sure to make a backup copy and keep your original to safe place and only use the backup when trying to restore your old wallet.

Can you try to open the old wallet file what it looks like?
Because before if the wallet is not encrypted you can able to read the wallet file so if your wallet file is not encrypted you can directly open it through notepad and you will see all used public and private keys. You can copy them and proceed with importing private keys to Electrum.


If it was encrypted and you forgot the password you might need to use BTCrecovery tool source can be found from this link below

Also, check this post below for other solutions and it's a similar error as yours so you can use it as your reference.

I don't think you will need to do that on Antminer t15 the j4 pin jumper is only for the Antminer s9 control board or any similar control board.

If you are going to flash the t15 through an SD card you will need to copy and paste the firmware inside the SD card and put the SD card to your T15 miner and run the miner. That's it you don't need to find the j4 pin, unlike the s9 miner.

What router do you have? Let me try to search the router if it supports Ovpn because it is easier to set up.

Mine is Tp-link it can easily set up with OpenVPN and I can remotely access my miner by using the same setup.
If your router is the same as mine you can check this youtube video how to setup Ovpn in your TP-link router https://www.youtube.com/watch?v=A96nOgReUIM

Try to contact this man "taserz" he mostly has tools for disabling signature check and unlocking SSH. I don't if he has a tool for t15 but just try to contact him and maybe he is developing a new tool that supports T15.

I think you don't know yet about flashing it through an SD card?
You might be trying to flash your unit through WebGUI and receive some error?
What you should do if you want a successful flashing is by flashing it through an SD card.

On the first question, I think you make a self-moderated topic with or without reason but only make a self-moderated topic if you do not want spam and want to make your thread healthy.
Take note there are some sections that you can't make self-moderated like here in the meta section.
Try to make a thread on service discussion click the new topic and look for an "advanced options" and check this




For your 2nd question, anyone I think can make a poll if you don't know how to make a poll you can easily make a pool by clicking this below


And then this is what you will see on poll creation.


About your 3rd question, you can't block them to see your thread or post but you can block users if you don't want to see their thread or posts.

Why not tell us what website you are trying to recover your wallet with your 17 words passphrase?

17 words seed phrase is generated mostly on Blockchain wallet and if you want to convert them into 12 words seed then there is no way to do that.
I suggest you follow what others said above by clicking the recovery and paste your 17 words seed phrase and then it will show the login link including the password.

Now if you want to have a 12 words seed phrase then download Electrum from here https://electrum.org/#download It will generate 12 words seed phrase.

After you generated a wallet from Electrum the funds you recover from blockchain, you can send them all to your Electrum. Make sure that you have 12 words seed backup for future recovery.

There is no Hardware wallet called Treasure you might be talking about Trezor wallet?

For online wallet, it's already mentioned above but I do not recommend you to use Blockchain.com wallet because it's a buggy web wallet and for Android, you can use Mycelium as mentioned above but Electrum also has an Android version so try that first.

Other mobile wallets can be found here https://bitcoin.org/en/choose-your-wallet?step=5&platform=android

For a web wallet that you can run offline use this https://coinb.in/#wallet

We can't say which firmware is the best option because they are many competitors with unique features.
What exactly error do you get when flashing it with hiveos firmware? You might do the wrong procedure when flashing the miner with HiveOS?


Anyway, did you check the awesomeminer? It seems they support Antminer t15 check the official thread below.

If you still got some error while flashing it might be a signature check you will need firmware that can bypass or remove the signature check.

If you know SEO like mk4 said you will get passive traffic but doing SEO it's not easy there are two types of SEO strategy off-page and on-page SEO.

If you want to learn to do these both I suggest you look for backlinko website or this link below
- https://backlinko.com/seo-this-year

If you learn both off-page and on-page SEO I'm sure you will gain huge traffic and get a larger number of referrals.

Check this list of tools for SEO below

They will work if you can bypass the "fan sensor" and give a fake signal but mostly they don't need any device(Fan simulator) just to bypass the fan check. You can bypass the fan check on different firmware like in Braiins OS.

Their official thread can be found here https://bitcointalk.org/index.php?topic=5036844.0
And you can read about disabling fan from here https://bitcointalk.org/index.php?topic=5036844.msg49918016#msg49918016

There are two types of wallets on Electrum Legacy or Segwit wallet. What wallet did you generate Segwit or Legacy?

The address generated from legacy looks like this below


For Segwit or Bech32 this is what it looks like


The Segwit one is not yet supported on some websites so maybe the website where you want to withdraw BTC Segwit is not supported yet.

You can make a screenshot or tell us what is the first 3 letters of the address you use so that we can identify exactly the issue here.

Yes, it was and it works without entering the password you can recreate a new account the electrum version is 4.0.3 and it seems all new versions disable this?

3.3.8 version you can't make a new account the same as the latest Electrum 4.1.4 I already check on my old phone without wifi.

It seems the issue is only for 4.1.4 because I can able to make a new wallet on an older version look below.(Luckily not yet upgraded to the latest version)



The button is not greyed out unlike yours.

The Crypto tab is paying but the only problem is they are cheating and you earn less compared to mining with your own.

I suggest you learn deep about mining altcoin because you can only mine in CPU with an altcoin. But if you want to mine Bitcoin I suggest you read this link below first.

- https://bitcointalk.org/index.php?topic=4636521.0

And only ASIC machines can mine Bitcoin like Antminer s9.

It shows 0 ASIC to all Hashboard.

Have you tried to flash it with different firmware?

If you already did then the issue is the hardware. I heard someone solve his issue by disassembling the unit and cleaning the hashboard there might be shorted part that is why all hashboard shows no ASIC chips.

Can you follow the guide from this link below on how to configure the external drive for your raspi

- https://howchoo.com/bitcoin/run-bitcoin-full-node-raspberry-pi#configure-the-external-hard-drive

It needs to configure the external drive first before you are able to use and write data to your external drive. I don't know if there is a difference between using HDD and SSD.

This is not clear I would like to know if how did you reset is it the PC or the Bitcoin core wallet?

Actually, there is no reset button on the Bitcoin core wallet so I guess it was your PC?

If it was your PC then it won't be easy to recover the wallet you might need to use some 3rd party software like Easus file recovery.

Can you try to install everything and use that thing to search on "wallet.dat" let's see if it can find two wallet.dat on different folder.

There are some people here who make reviews for miners check this user "HagssFIN" it has some whatsminer reviews and guide under his signature.

About manufacturing, I think they don't have a company outside "Beijing, China"

Do you put a fan on the hashboard while running it with the test fixture or zeus tester as you call it?

Without the fan, it will automatically shut down due to overheating.
